e0“The second foliar leaves of Cheyenne, a drought-hardy, and Ponca, a drought-susceptible variety of winter wheat were compared anatomically before and after subjection to specific periods of moisture stress”
e4“When rewatered after 4 days of drought, 75% of the Cheyenne plants survived, but variety Ponca showed only 63% survival”
Title
Anatomical Variations in the Wheat Leaf Following Internal Water Stress

Other claims from this paper (10)
- Observation In untreated plants, Ponca had relatively larger amounts of xylem tissue than Cheyenne.
- Observation In untreated plants, Cheyenne had a greater proportion of sclerenchyma tissue than Ponca.
- Intervention effect Water stress thickened leaf cell walls of wheat.
- Intervention effect Water stress increased lignin deposition in xylem elements and bundle sheath cells of wheat leaves.
- Intervention effect Water stress caused progressive plasmolysis in nuclei and plastids of wheat leaves.
- Association The degree of anatomical disorganization was greater in Ponca than in Cheyenne, as correlated with internal moisture stress.
- Association Water content level in the tissue was related to anatomical changes in stressed wheat leaves; the direction is not stated.
- Intervention effect Only 63% of Ponca plants survived when rewatered after 4 days of drought.
- Mechanism The differential drought response of the two varieties may partly reflect underlying physiological differences that account for the greater drought resistance of Cheyenne.
- Intervention effect Stressed wheat leaves showed pronounced wilting after more than 4 days of drought.
